Abstract: PURPOSE:To check leakage of gas sealed in a bladder during operation of a main engine by disposing a stop valve and a flow indicator in a connection pipe to an adjacent bladder type hydro-pneumatic accumulator. CONSTITUTION:Gas pressure portions in bladders of plural bladder type hydro- pneumatic accumulators 8 are connected to each other, and stop valves 41, 43, 45 and flow indicators 40, 42, 44 are disposed in the respective connecting pipes between the accumulators 8.
